We've done breaks like this before via Andrew. We did boxes of Leaf Oval Office, which were like $1,500 a box and we had slots for like $50 or something idk. It was fun. I clearly never won but I paid for spots in each break. This would be similar but could be multiple winners. One for the set, one for the box top, etc. etc. etc.
80 base cards
3 autos
1 slambalaya
1 boxtopper
85 slots (some of the base bring +$10)
Each slot would be close to $40 for a shot at a bad bad card.
